Kasteel Sterkenburg

Driebergen-Rijsenburg, Netherlands, Netherlands

---

Kasteel Sterkenburg is a medieval moated castle originating in the mid-13th century as a round tower house on an island near Driebergen-Rijsenburg in Utrecht province, Netherlands, likely initiated by knight Gijsbrecht van Wulven and completed by his son Ernst. Recognized as a ridderhofstad in 1536, it saw expansions, demolitions, and rebuilds—including 18th-century alterations by Jan Verkerk and major 1848-1851 neo-Gothic renovations under owner Karel Johan Kneppelhout that created its current block-like main building flanked by the preserved 13th-century round tower and a 1867 square tower. The site features a double bridge, landscaped park, zinc balustrades, and original interiors like lambrizages, now functioning as a bed-and-breakfast within its Rijksmonument-protected estate.
